TPMS is an abbreviation of Tyre Pressure Monitoring Systems, which are electronic systems which monitor tyre pressure and temperature. They inform drivers of the low pressure or sudden deflation of tyres.
These systems transmit data to the vehicle’s ECU and are depicted via a pictogram display, voice activation or a simple warning light within the vehicle.
There are 2 main types of systems. Indirect and direct systems.
Indirect TPMS System
The vehicle’s ECU/ESC uses the ABS sensors to calculate the rate at which each wheel rotates, determining if a tyre has a reduction in pressure about the other wheels.
Direct Fit System
Consists of a TPMS sensor installed directly on to the valve of each wheel. The sensors use radio frequencies to transmit the data to the ECU.
These sensors send real-time information about the tyre’s pressure and temperature through RF signals to the vehicle’s ECU.
Reasons to replace TPMS sensors
Common reasons for replacing the vehicle’s TPMS sensors include:
- Tyre changing has physically broken the sensor
- Battery depleted
- Stem damaged or corroded (Stems can be provided separately)
- Incorrect or not performing the relearning procedure
Mobiletron offers a range of sensors in universal (programmable) or direct fit (pre-programmed). To view our full range of TPMS sensors, please click here.
